Product Usage:

Concrete resistivity tester, also known as potential detector (corrosion analyzer), is used to measure the electrical resistivity of concrete. The corrosion of steel bars in concrete is an electrochemical process that generates an electric current to dissociate the metal. The lower the electrical resistivity, the easier the corrosion current flows through the concrete, and the greater the possibility of corrosion. Therefore, measuring the electrical resistivity of concrete can effectively evaluate its corrosion resistance and assess the degree of corrosion of existing steel bars.
